Pretreatment loss to follow-up (PTLFU) is a barrier tuberculosis (TB) control in India's Revised National TB Control Programme (RNTCP). PTLFU studies have not been conducted mega-cities, where patient mobility may complicate linkage care. We collected data from registries for May 2015 22 RNTCP designated microscopy centers (DMCs) Chennai and audited addresses phone numbers patients evaluated suspected understand how missing contact information contribute PTLFU.

Introduction Pretreatment loss to follow-up (PTLFU)—dropout of patients after diagnosis but before treatment registration—is a major gap in tuberculosis (TB) care India and globally. Patient healthcare worker (HCW) perspectives are critical for developing interventions reduce PTLFU. Methods We tracked smear-positive TB diagnosed via sputum microscopy from 22 diagnostic centres Chennai, one India’s largest cities.

One-fifth of people with drug-resistance tuberculosis (DR-TB) who were initiated on newer shorter treatment regimen (with injection) had unfavourable outcomes in India as 2020. Evidence self-driven solutions and resilience adapted by DR-TB (PwDR-TB) towards their multi-dimensional disease challenges are scarce globally, which we aimed to understand.

In the government TB program Chennai, India's fourth most populous city, there 49% gap between official number smear-positive patients diagnosed and registered treatment within city 2014. We hypothesize that this "urban registration gap" partly due rural temporarily visiting for diagnostic evaluation. Methods collected data one month (May 2015) from 22...
